For a long time, together with horizontal lacquered boards engraved with Chinese characters, parallel sentences written on crimson paper, ornamental kumquat and peach trees, and popular Hang Trong and Dong Ho pictures, the five‑fruit tray prepared for Tet has transcended its material value to become a spiritual symbol, an original national product in the spiritual life of the Vietnamese.

At present, while many of the ancient spiritual values have sunk into oblivion, the custom of arranging the five‑fruit tray on the altar during the lunar New Year days is being jealously preserved as a fine legacy of Vietnam's traditional culture. The buying of votive offerings and the decoration of ancestral altars during the traditional New Year days are closely connected with the rituals of worship practiced by the Vietnamese towards their ancestors.

During these New Year days, in addition to such national dishes and products as "Fat pork, salted onions, parallel sentences written on red paper. Long bamboo poles planted upright, strings of fireworks, and square glutinous rice cakes", it is indispensable for each Vietnamese family to display a five‑fruit tray on the ancestral altar for Tet.

One theory says that the five fruits are symbolic of the five basic elements of oriental philosophy - metal, wood, water, fire and soil. Other theories regard the tray as symbolic of the fruits of a family's hard work throughout the past year, which are consecrated to heaven and earth and their ancestors as sign of respect and gratitude.

The custom of displaying the five‑fruit tray as votive offerings at the holy place of the house has been reflected in many popular legends and tales. It has originated from ancient popular beliefs observed from one generation to another in their worship towards their forefathers. To this day, the Vietnamese still observe a long‑standing custom of placing the first ripe fruits harvested from the home garden on the altar and burning incense sticks in memory of their ancestors.

The “Mam Ngu Qua” in Tet Festival represent the quintessence that Heaven and Earth bless humans. This is one of the general perceptions of life of the Vietnamese, which is “Ăn quả nhớ kẻ trồng cây” ("When taking fruit, you should think of the grower")
